d,l-11-Nor-delta9-THC carboxylic acid glucuronide (mix of isomers)
[CAS Number N/A] 11-Nor-Δ9-THC carboxylic acid glucuronide is a major urinary metabolite of Δ9-THC. Use of a THC acid glucuronide standard is helpful in controlling the hydrolysis efficiency when using GC/MS methods. With LC-MS/MS method, a direct determination of both THC-COOH and THC-COOH glucuronide can be done without the hydrolysis step. THC acid glucuronide is currently available from LIPOMED as a ready-to-use 0.1 mg/ml calibrated standard solution. Special storage & shipping requirements.
